Soak the pot in water once a month to make sure the potting mix is well hydrated. Do not overwater your Boston Fern. Test the soil with a bare finger, if it feels dry then water it.
Dust the leaves regularly using a soft brush. Dust can clog up the pores of the leaves and make it difficult for the leaves to function properly.
Lightly prune in winter to keep the plant ‘tidy’ as desired.
